Science 8:  Today I handed back pg 143 # 1-9 and we marked pg 154 # 1-5,11,12.  We drew ray diagrams to show how shadows form, and we confirmed the Law of Reflection using Ray Boxes, baffles, and mirrors.  In the last few minutes we watched this clip on the Electromagnetic Spectrum.

Chemistry 11:  We wrote the Reactions Unit Test today.  Unit 8 # 13-19 & 22 are due on Wednesday.  Lab 20C is due Friday.

Chemistry 12: I checked unit 4 # 39 & 40.  We took notes on pH and pOH, then we read section 4.10 and did Problems #49-57 which are due Thursday.  I need to check unit 4 # 31-37 for some of you still.
